Researchers at a university in the Republic of Ireland are calling on the public to take part in a study which will examine whether recreational waters contain dangerous antibiotic-resistant superbugs.
The study is being launched after the team found potentially deadly bugs in the waters around Galway.
Scientists at NUI Galway want 300 people to volunteer for the project, which will also explore how superbugs get into human populations.
The team of researchers plan to test two different groups of 150 people, one made up of those who regularly use lakes, rivers or seas, the other comprising those who rarely enter the water.
Dearbhaile Morris, the lead investigator on the project, said that antibiotic-resistant bacteria are often harmless, unless they get into a wound, the bladder or the blood.
«This mostly happens in sick or vulnerable people with weaker immune systems, such as those in intensive care, the very old or the very young, and special antibiotics are then required for treatment, as ordinary antibiotics do not work,» she said.
Dr Liam Burke, who will also be working on the study, said that superbugs are common in recreational water because of the increased use of antibiotics in humans and animals, and because sewage and manure ends up there.
Despite the country having some of the cleanest bathing waters in Europe, raw sewage is still being released in more than 30 places.
Dr Burke added: «If hospital waste ends up in the sea, it will more than likely contain antibiotic-resistant bacteria or a slurry stream from a farm ends up getting into the water or river, then there is potential for that to contain a high level of antibiotic-resistant bacteria.
«As the superbugs have been exposed to antibiotics, they needed to develop a mechanism to resist it. They don’t cause problems in healthy people if they stay in the gut, but if they get out of your gut by not practising good hygiene, then you could spread them around the home.
«A young child or elderly person could then pick it up.»
Anyone over the age of 18 in Ireland can take part in the study.
